如何简单使用

1. 创建实体类

@Entity
public class Book {
    @Id
    Long id;

    String title;

    String author;

   ......
}

2.继承PanacheEntity

@Entity
public class Book extends PanacheEntity {
...
}

3.使用

PanacheQuery<PanacheEntityBase> all = Book.findAll(Sort.by("id", Sort.Direction.Descending));
return Result.ok(all.firstResult());

4.分页查询

PanacheQuery<Book> all = Book.findAll(Sort.by("id", Sort.Direction.Descending)).page(dto.getCurrentPage() - 1, dto.getPageSize());

5.保存数据

Book book = new Book();
book.title = "Java";
book.author = "xxx";
book.persist();

6.删除数据

Book book = Book.findById(1L);
book.delete();
